I deal with so many programs, websites and services that I often forget my passwords. No doubt this happens to other Linux users as well so here is the solution –KeePass. It is a free and open source password manager that helps you manage and keep your passwords securely.

KeePassstores all your passwords in a single database locked with a master key. Because of this, you must remember a single master key to access the database.

All passwords are encrypted using the most secure encryption algorithms. In fact,KeePassis compatible withadvanced encryption standard(AES, Rijndael) and the Twofish algorithm.
